To all whom z'tmay concern:

Be it; known that 1, GHANNELL L. Saus- DERS, S12, a citizen ofthe United States, resid ing at Berwick, in the parish of Saint. Mary and State of Louisiana, have invented. cer tain new and useful Improvements inTanks; and I do hereby declare the followingto be a full-,clear, and exact descriptionof the invention, such as will enable others skilled in the art to which it appertains'to make and use the same.

This invention relates to new. and useful improvements in tanks and has for its object the provision of device which will permit the repair of the valves in such tanks with out the necessity of emptying the tank of its contents.

Another object of my invention is the pro vision of such a device which will be separate from the tankand form a well which will form a manhole of sufficient size to permit a workman to enter said well and repair the valve contained; in the tank.

lVith the above and other objects in view I will now proceed to describe my invention in the following specification and accompanying drawings, in which,

Figure 1 is a sectional view through a fragment of a railroad tank showing my improved device applied thereto,

Fig. 2 is a detail sectional view taken on line 22 of Fig. 1,

Fig. 3 is an enlarged detail sectional view of the auxiliary valve,

Fig. 1 is a top plan view of a fragment of my improved tank,

Fig. 5 is an enlarged detail sectional View of the outlet valve, and

Fig. 6 is a transverse sectional view taken on line 66 of Fig. 5.

Referring to the drawings by characters of reference 1 indicates the bottom of my improved, tank, having extending upwardly from the edges thereof the sides 2, these sides being preferably formed of sheet metal and riveted as clearly illustrated in the drawings. A vertically disposed auxiliary wall 3 is secured to the bottom 1, as clearly shown at i and terminates at each extremity in the angularly extending Walls 5 and 6 which are firmly secured to the wall 3 to form a water tight joint. The opposite ends of the walls 5 and 6 are preferably riveted or otherwise secured to the upstanding wall 2 of the tank, as clearly illustrated at 7, and are so arrangedjthat no Water will be permitted to enter the wall thus formed between the end of the wall 5 and the walls 2. A suitable ladder 8 is secured to the wall 5 as will be clearly seen upon referring to the drawings and is adapted to form a means of ingress from the top of the tank to permit; a workman to enter.

Immediately adjacent the lower extremity of the wall 3 and centrally located with relatlon thereto I preferably provide the aperture 9 through which the water from the tank is adapted to enter the well. A suitableqcollar 10 is secured to the wall 3 by means of the flanges 11 which are heldthcrcto by means of rivets or other suitable fas' teners. This collar 10 extends outwardly, as clearly illustrated, and terminates in an angular valve seat 12, this valve seat being inclined preferably at an angle of substantially 45 degrees with relation to the collar and is internally beveled to snugly receive the inwardly extending portion or boss 13 formed on the flap valve 11 which is pivotally secured to an ear 15 formed on the upper portion. of the collar 10, as will be clearly seen upon referring to Fig. 3 of the draw ingsi Adjacent the lower edge of the flap valve at a, point substantially diametrically opposite. the pivot I preferably provide a loop. 16 which is adapted to cooperate with an apertured rod. 17 extending upwardly to the top of the tank. This rod is adapted to control the valve when the device is in use.

A suitable aperture 18 is formed on the bottom of the well and communicates with a pipe 19 which is secured to the bottom by means of a flange 20, this flange 20 being adapted to receive rivets or bolts and thereby hold the pipe 19 in position. A collar 21 is provided and secured to the bottom wall on the side opposite the pipe 19. The aperture through this collar is adapted to register with the aperture 18 in the bottom and form a passage through which the liquid contained in the tank is adapted to be withdrawn. This collar 21 has a flange 22 formed integral therewith which is adapted to be secured to the bottom by means of any suitable attachment. A valve seat 23 is formed at the upper extremity of the collar and provides a means to form a tight joint between the valve 24 and said collar. Centrally located of this valve 24 I preferably provide the upstanding ears 25 to which is pivotally secured the lever 26, having the downwardly extending angular portion 27 formed at one end thereof. This downwardly extending portion 27 preferably terminates in an apertured member which is adapted to cooperate with the ear 28 and pivotally secure the lever with relation to the bottom of the tank as will be clearly seen upon referring to Fig. 5. The end of the lever opposite the angularly extending mem ber 27 is preferably apertured as clearly illustrated and adapted to cooperate with a bar 29 which extends upwardly to a suitable operating mechanism which is adapted to be actuated from the outside of the tank and permit the liquid within the tank to flow through the valve and into the pipe 19. The pipe 19 is extended as clearly illustrated and terminates in the usual knuckle joint 30 which is provided with the ordinary pipe through which liquid contained in the tank is conducted when the device is in use.

A draining valve 31 is secured to the bottom of the tank and communicates with the interior of the well, this valve 31 being preferably of the ordinary globe type is adapted to form an outlet through which the liquid contained in the well may be withdrawn when it is required that repairs be made to the outlet valve, described in the above paragraph,

It will be clearly seen from the foregoing that when my device is in'use and under ordinary circumstances the valve 14 is left open, thus permitting the liquid contained in the main part of the tank to flow into the well and out through the outlet valve 24. In its open position, the valve 14 is supported in an inclined position upon the auxiliary wall or partition 3. Should at any time it be desirable to examine or repair the outlet valve, the valve 14 is closed and the drain liquid contained in the well will be withdrawn through the drain valve and a Workmanmay then descend into the well to make any necessary repairs. After such repairs are made the device is again in operative valve 31 opened. It will be obvious that the parts without in. anyway departing from the spirit and scope 'of my invention.

What I claim is: l 1

In a device of the character described, a

tank, a vertical partition positioned in: said tank and arranged relatively near the-side l wall thereof, side partitions extending from said vertical partition to the side wallof the tank and forming asubstantially rectangular well, said well extending from the bot:

tom of the tank to the upper edge thereof,

an inlet valve arranged in one side wall of the well and connecting the same. with the main body of the tank, meansextending to I the top of the tank for controlling the valve,
